Hello! Love the theme and how much expansion potential it has with a balanced skill system. The asynchronous co-op aspect reminds me of other players' chips left behind in NieR:Automata or other players sacrificing their saves to aid others. I would love it if the sacrifice hits harder with a bigger reward for another player, truly giving something significant away - but that would also require balancing combat aspects because I found some ground graphic attacks taking away more health than I'd find "challenging in a fun way". This can just be personal taste in terms of player difficulty but definitely something worth exploring :)
